rsf2csf

Convert real Schur form to complex Schur form

Syntax

[U,T] = rsf2csf(U,T)

Description

The complex Schur form of a matrix is upper
triangular with the eigenvalues of the matrix on the diagonal. The real
Schur form has the real eigenvalues on the diagonal and
the complex eigenvalues in 2-by-2 blocks on the diagonal.

[U,T] = rsf2csf(U,T)converts the real Schur form to the
complex form.

Arguments U and T represent
the unitary and Schur forms of a matrix A, respectively,
that satisfy the relationships: A = U*T*U' and U'*U = eye(size(A)).
See schur for details.

Examples

Given matrix A,

1 1 1 3
1 2 1 1
1 1 3 1
-2 1 1 4

with the eigenvalues

4.8121 1.9202 + 1.4742i 1.9202 + 1.4742i 1.3474
